What is Ceramic Pipe Sleeve

What is Ceramic Pipe Sleeve

Ceramic pipe sleeves are protective linings made from advanced ceramic materials, designed to enhance the durability and lifespan of pipes in various industrial applications. They offer exceptional resistance to abrasion, corrosion, and high temperatures, making them ideal for challenging environments.

These sleeves are typically produced using a combination of high-purity alumina and other ceramic materials, which are processed at high temperatures to create a dense, wear-resistant lining. The result is a product that can withstand the rigors of heavy use while maintaining its structural integrity.

Recently, 95% alumina ceramic sleeve-lined pipes , elbows, and T-joints have been widely adopted in lithium battery material conveying systems .

Producing large-diameter ceramic sleeves poses a significant challenge for most manufacturers due to difficulty in controlling deformation during sintering. Furthermore, it requires advanced isostatic pressing equipment to ensure dimensional precision and structural stability.

Successfully manufacturing these high-precision components is a strong indicator of a company’s production capabilities and technical expertise in ceramic processing.

At present, our factory owns both the state-of-the-art wear-resistant ceramic pressing facilities and the engineering know-how to deliver reliable, large-size ceramic sleeves tailored for demanding industrial applications.

The combination of ceramic’s high rigidity and steel’s elasticity makes ceramic-lined pipes outstanding in abrasion, heat, and corrosion resistance. These pipes are widely applied in  power generation, metallurgy, mining, and chemical industries, offering significant advantages over conventional steel, cast stone, and steel-plastic composite pipes.

304 stainless steel plate has very good formability and can be readily welded by all common methods. Its combination with ceramic lining offers enhanced performance in wear resistance and structural stability.

Manufacturing Process of Ceramic Sleeve Lined Pipe

Ceramic sleeve lined pipes are engineered by embedding a high-purity alumina ceramic sleeve into a robust steel outer pipe. This combination significantly improves resistance to wear, corrosion, and extends service life in highly demanding environments.

Ceramic Sleeve Preparation
Ceramic Sleeve Preparation
  • Material Selection: High-density alumina (≥95%) for superior abrasion and chemical resistance.
  • Precision Shaping: Formed by isostatic pressing and sintered at ~1700°C.
  • Surface Treatment: External surfaces roughened for enhanced adhesive bonding.
Steel Pipe Preparation
Steel Pipe Preparation
  • Material Selection: Carbon or stainless steel based on strength and corrosion requirements.
  • Surface Cleaning: Inner walls cleaned and roughened to improve bonding strength.
Bonding Process
Ceramic-to-Steel Bonding
  • Adhesive Application: Heat-resistant epoxy is applied uniformly to contact surfaces.
  • Assembly: The ceramic sleeve is precisely inserted into the steel pipe.
  • Curing: Adhesive is cured for 24–48 hours to ensure structural integrity.
Finishing and Quality Control
Finishing & Quality Control
  • Flange Installation: Flanges or threaded ends are added for system connection.
  • Inspection: Dimensional, visual, and pressure tests ensure quality standards.

Detailed Installation Process

1. Surface Cleaning

Thoroughly remove rust and debris from the steel pipe surface to ensure optimal adhesion.

2. Binder Preparation
  • Mix binder parts A & B in correct ratio.
  • Stir at least 4 times for even consistency.
  • Mix filler thoroughly if added (3 additional stirs).
3. Adhesive Application
  • Apply 0.5 mm adhesive to inner steel wall.
  • Apply 0.5–1 mm on outer surface of ceramic sleeve.
  • Seal joint surfaces between ceramic rings.
4. Sleeve Insertion & Sealing

Install sleeves precisely. Fill any gaps and seal joints to ensure a continuous ceramic layer inside.

5. Threading & Grooving
  • Process NPT male & female threads on pipe ends.
  • Chamfer edges (1×45°) for safety.
  • Apply protective oil to threads.
6. Final Curing & Check
  • Do not move pipe before curing is complete.
  • Allow ≥ 48 hours curing time (longer in cold).
  • Check alignment and joint integrity after cure.
